Clock mutants of Drosophila melanogaster

R J Konopka et al. Proc Natl Acad Sci U S A. 1971 Sep.

Abstract

Three mutants have been isolated in which the normal 24-hour rhythm is drastically changed. One mutant is arrhythmic; another has a period of 19 hr; a third has a period of 28 hr. Both the eclosion rhythm of a population and the locomotor activity of individual flies are affected. All these mutations appear to involve the same functional gene on the X chromosome.
